In the final example, we used when i.e. switch statement is used to print the case statement on the console with forEach loop iteration. Conclusion In the kotlin language, we used different kinds of loops to store and retrieve the elements for the iterating process. Also, the iteration st...
In the example, we generate a random number. Based on the random value, we print a message to the console. Kotlin while loopThe while keyword is used to create a loop. It runs until the given condition is met. while_loop.kt package com.zetcode fun main() { var i:Int = 0 while(...

When you run the above Kotlin program, it will generate the following output:1 2 3 4 5 Let's see one more example where the loop will iterate through another range, but this time it will step down instead of stepping up as in the above example:...
In Kotlin, You can useifas an expression instead of a statement. For example, you can assign the result of anif-elseexpression to a variable. Let’s rewrite theif-elseexample of finding the maximum of two numbers that we saw in the previous section as an expression - ...
